Application filed 4May 28, 1910. Serial No. 563,852. i

.To all whom it may concern;

Be it known that I, ADoLPHUs H. Fonsi'- NER, a citizenof the United States, and a resident of Portland,in the countyof Multnomah and State of Oregon,`have invented a new and Improved Oil-Burner, of Which the following is ajull, clear, and exact description.

present invention has 1n View are.: .to provide a burner Whereih is secured a erfect admixf l ture of oil yand air; toprovi e la spiral ro.

tary mixing member for controlling the loW of elements. to the burner`- orifice; and to provide `a removable burner xture ada ted to be removed from the supply pipe an ar-4 ranged toi be disassembled for repair-or replacement.

One embodimentof the present invention is.-4 disclosed in the structure illustratedin the accompanying drawings,` in which like characters of reference denote corresponding parts in all theiriews, and in which- Figure 1 is a side` elevation of a burner fixture shown as applied to the side Wall of a furnace, said side Wall being shown` `in section; Fig. 2 is a longitudinal section of the burner fixture and supply pipes connected therewith; Fig. .3 is a'vside elevation of a bearing plug-- supporter "used in connection with the present invention; Fig. 4 is -an .end view of the bearing plug shown in Fig. 3, viewed from the bearing end;` Fig. 5 is a side view of an eliminating screen; and Fig- Gis an enlarged view in detail, showing the face of theburner tip.-

The inventionis specially applicable for.'

use .in furnaces, and where'it is desired to employ heavy base 011s. To assist 1n the carburetion Where 011 of thelcharacter s'p'ecl'- fiedy is-employed I have pmvided a iniXinO' au:

` a b nected with a t-ube 20, Whereinis supported `an eliminating screen 21. The eliminating chamber,` which in the present'v construction isformed by a pipe section 7. Thepipe sec-v ftion l7 is suitably threaded to fit the head 8 of ana-ngle connection 9, to which an oil supply pipe 10 and an air supply pipe 11. ed. The feeding devices are rigidly atta for advancing t e supply of oil and aiu eni- .ployed in connection with this. burner are not shown in the drawings. These devices may be of any known character "suitable for the purpose -for which they are designed.

Within the pipe section 7 and rotativelyi4 uiounted therein, is a spiral propelling blade 12. The blade l2 is rota-tively mounted in said section, and for this purpose is pro lprincipal bjects vvhich thev vided at each end vvith pivot spindle extensions 13, 13. The spindles 13,13 are coned at V- theend, and the cones are seated in inverted conlcal bearing cups 14. formed in the end of each of the bearing plugs 15,15. The plugs l ended set screws, andare provided Wit 'square wrench heads 13.1,;16 whereby they may be rotated to adjust the bearing cups to the spindles 18. Each of the vlugs 15 is provided .with a jam nut 17, whereby the eing adjusted. l

The-.plugs 15 are carried in supporters 18, 118, which are cyliendrical 'in shape, having an outside di'amet plugs are held immovable in position after r of lessthan the inside f` .1.5, 15 are silnilarin construction to cupl diameter ,ofthe pipese'ction .7. .The cylinf" drical portions of the plugs 18 are provided with .lateral Wingextensions 19, 19, themiter4 edgeswhereof are extended ytothe` outer skln of the section 7., and' are there provided with segment-al screw threads adapted to aline with the screw Athreads of the ends off the section 7.' The ends of the section 7 are slot-ted longitudinally to receive in holdingrelationthe Wing extensions 1.9..; In manufact'uringfthe mixing chamber, vthe slotsfare cutvin the .endsof. th section 7 toreceive the wing-extensions 19, 19fprior to the union thread lbei ,0' formed on' the ends of the said section.A 'W enthefunion thread is formed,

.the Wings19f19 Jand supporters 18":j1rey held in .position on 'the section 7 so that the thread Whichis cut inlth'e pipe section 7 is simultaneously'fcut in vthe outer edge of thefwings 19, '1-9. By thislarangiement, when the pipe section 7 is` screwed into the unions by which: it is held in position, the supporters are, at the s me time, screwed into land held by the said unions.

The outer end of the pipe section 7 is conscreen 2,1is constructed from perforated material in the form of a disk. The 'purpose of the screen is' toipreventthe flashing back from theY b'ui'nei' tip. The tube 2O is, at the point of connection with the section 7 of the f same diameter,as the said section, and is provided with a -screw thread similar in` pitch and adapted to engagea coupling 22.

The coupling 22 is' of usual construction as employed inl connecting tubes. or pipes. of similar character to that specified.

At the outer end rof the tube 20" is con` nected a burne'r fixture 23. The fixture 23 i s"p1"ov1dedI with a `solid and enlarged tip 24, which may be constructed from any suitablerefractory material, The shank or body ofthe ixturej28 is threaded, as shown in 5 the drawings, toreceive a coupling 25, which -is also connected with the threaded end of the .tube 201 'All the coupling joints, it Will beunderstood, 'are ,formed gas-tight by the IuS'uaLmethOd. I lo 'The tip 24is provided at` the outer end Withfa spreading slet 26, usually' formed by a Saw.v cut `extending across the head of the tip. .Communicating with the slot 2G, and piercingv inwardly the body of the tip, is a small ductf27. Atthe inner end of the jduct 27 the assage thereof is gradually in creased to orm an' inverted cone-shaped passageopening into the duct 27. Extend ed Within the 'cone-shaped end of the duct 27 20,is a' small perforated metal, cone 28. The

' y, baseof the cone 28 issuthciently extended to .touch the entire inner surface of the .shank 1. of the xture 23, and .toy `form a closure there- 'Ztor, compellingfthe oil to pass through the cone 28` preliminary vto introduction through the dnct 27. `to the v:spreading slot 26, Where it is burned. i 1 y The operation of a system supplied with a burner of the` character specified resembles, 30 as to thevmcthod of introduction of the air and.ailftlie systems at present in vogue..

Whemiii thepresent. burner, the oil and air ,Y are, received :from'the pipes l0 and 11. tlniy are advanced rapidly past the Wings.y l9l9 of. the supporters 18, and impinge upon the l vspiral'` plate l2. The plate l2, yielding un# dergthe direct 'thrust of the onrushing"` air and oil, rotates ymore or less rapidly asfthe air pressureis yincreased or diminished. The '4 0 oilr is drawn` from the pipe, and when brought in contact with the'rushing air, is, by the air, comminuted. 'After bein com- 'minuted it is carried inthe shape o globf ules into thefmixing chamber formed by the 4.5 pipe section 7, and therein impinges upon .the spiral surface of the plate 12. Upon the plate l2 is thus formed a coating of oil. .In the subsequent and continuous action of the burner, the air, in passing through the spiral channel formed by the plate l2, is brought into intimate contact with the oil at all stages of its passage through thc mixing chamber. The oil impregnated or oil .laden air, after passing from the mixing chamber, enters'the tube 20, where any globules of oil or solid matter are arrested by the eliminating screen 21. Beyond the screen 2l the mixed airand oil, is passed to the cone 28, and through 'the same and the duct 27, to the spreadingislot 26 to be burned.

Having thus described my. invention, what I claim as new and desire to secure by Letters 'Patent is y l. An oil burner, comprising a supply pipe; a burner fixture; a mixing chamber interposed between said supply pipe and said burner fixture `to form a comn'umicating passage between the same; an elmlgated spiral member rotatively mounted in said chamber; adjustable bearings for said spiral member; and supports for said bearings having laterally extended wings mounted iu.

slots formed on the ends of said chamber.

2. An oil burner, comprising separate air and oilsupplies and connecting duets lhercforga mixing chamber therefor; a tube connected to' said mixing chamber and having an eliminating screen across the passage thereof; a bu-rncr fixture having a centrally disposed gas duct; and a metallic conc mounted in said'fixture to be heated thereby. In testimony whereof I have signedthis specification in the presence of two subscribing witnesses'.
